P4 2.2GHz Overclocked to 3.5GHz

explaining how a homemade nitrogen cooling system
overclocked a P4
from 2.2Ghz to an incredible 3.5ghz. There's plenty of stuff
to poke at over there. Update: 01/17 20:42 GMT by T : boaworm writes: "According to this paper, the Finnish geeks have successfully oveclocked a Pentium 4 to 3675 Mhz.

Laws to Punish Insecure Software Vendors?
Have a Happy.
given the many discussions on /. of late re: full disclosure of security holes, partial disclosure, disclosure to the company only, etc - what does the crowd here think of the way these exploits have been handled? The story says the Litchfield has commented publicly and explicitly on the nature of one of the holes that already has a patch available, but that he's holding close the holes that have patches still under development.
I guess another question would be, while Oracle is by no means a small company, if the company name started with an M and ended with 'icrosoft' would we be demanding more information?

The fact that defense in depth is a good idea does not justify allowing one of the layers to be weak. The defenses at every level should be as strong as possible, and that ideally means a bug-free app server and a bug-free database.
The only thing that this researcher proved is that in certain environments you can break in the system, which basicly holds true for every system.
No matter what, you can be sure that contrary to M$, these holes will be worked on 24/7 and fixed like yesterday. :)
Anyway, enjoy you uninformed, senseless bashing and flaming... trolls.
If programs would be read like poetry, most programmers would be Vogons.
The reality of it is that most DBAs, programmers and database developers in the working world scoffed at the ad campaign the moment it began. Sure, Oracle has a great product, but we all knew it wasn't bulletproof, no matter how may awards for "best of class security" it supposedly won.
The only real losers in this, other than organizations whose Oracle databases were victimized by a security flaw, were the corporate purchasers who were sold on the hype. They'll have to live with the fact that their DBMS isn't "unbreakable." Honestly, though, there are relatively few of those (none I can think of that are well-publicized, at least), as they are usually run on well locked-down *nix boxes.
It's not anything new. It's just agressive advertising. Some might argue that it's false advertising, but that's probably being a bit harsh. It's more like...overly boastful advertising.

It was a marketing ploy and any professional administator who looked at and said "wow, unbreakable, lets buy it" probably wasn't a professional at all.
It's not surprising that a system as complex as Oracle is going to have security flaws. However if you mistaken believed that Oracle had created the perfect piece of software, may I suggest you stow it away in the closet next to your Abdominizer and set of stay-sharp-steak-knives.
He who defends everything, defends nothing. -- Fredrick The Great
A software company said to the public, "Our product is unbreakable." The public replied, "No, you are not unbreakable."
Another software company said to the public, "Our product is not unbreakable." And the public replied, "You're right, you are not unbreakable."
The more I've thought about this, the more likely it seems. And a key aspect to this is that my OS vendor, SuSE, and ilk (Red Hat, Mandrake, etc) would be nailed just as much as MS, except with less money in the bank, they would be killed much more swiftly. Now, two of those are outside of the USA, so it's not a direct correlation, but there are some serious ramifications to software liability that occur in as reactive a society as we have today.
Certainly this announcement would instantly have a dozen law firms seeking people running Oracle to launch a multi-billion dollar suit of some flavor. And while certainly not "unbreakable", and (IMO) a bit overpriced, Oracle being available is a Good Thing. Of course they have holes. I'm equally sure that they will likely address them quickly (Quickly being relative to the company involved). Introducing *sane* liability (at least in America) is going to be very difficult in a society that is making it neigh impossible to be a medical doctor, and is driving up medical costs due to the extensive CYA documentation (videotapes, extensive reports, etc) now required by industry insurance.

This is pure bullshit. Are the programmers of
Apache, IIS, Half-Life, Quake 3 Arena, Perl, SSHD, glibc, wu_ftpd, or BIND at the middle school level? Windows NT? How about the linux kernel? All have had buffer overflows, and I'll bet that many of them still do.
Unfortunately it is not always as simple as "putting limits on characters". The simple fact is that the C language is practically designed to make buffer overflow bugs easy to write and easy to exploit.
I agree with you that buffer overflows are serious, though. That's why I think it is ridiculous that we still write security-critical network software in C. Sometimes it is hard to get around, like in the linux kernel when you need to do hardware access (a microkernel architecture might make it easier to write certain parts in higher-level languages). You might argue that performance would be impacted (I don't think this is true, especially with network software where the network is the real bottleneck), but even this argument falls through for 99% of users, since most users are far from full utilization of their processor. However, almost all users *are* affected by security holes.
More like, if all the software available on the x86 platform didn't depend on the chipset extentions rather than the raw architechture.
Don't confuse 'real life performance' with 'optimized for SSE/3DNOW/MMX' yadda yadda. Unfortuanetly, even though chips may be raw number crunching daemons (and Photoshop optimized for the G4 absolutely screams (maybe 33% better) over a faster clocked P4 in my first hand experience), and even though people may know that Mgz != speed, I think too many people still fail to remember that much of the percieved 'power' of certain chips come from compiler optmizations for that specific chip, not a lack of power in its competitors or an inability to turn FP and Int performance into 'real world' performance.
"Old man yells at systemd"
Can you really say that its the consumer who will win when no consumer programs require much processing power over a P2 400 or so?
I mean, it's nice that intel and AMD can make such fast processors, but where's the bottleneck on overall performance nowadays? I'm willing to bet it's not in the chip.
I think we've reached a point in personal computing where the software is years behind the hardware. Only in the fields of gaming or professional rendering do we need such high performance machines.
My friend's parents recently purchased a 1.5 Ghz Pentium 4 for day to day bookkeeping!
I have little time to look at nothing more than a booklet of pretty pictures

The P4 also has a less advanced FPU. When it comes to RC5 I guess there aren't as many clever little tricks you can use (like SSE), as the case is in 3d-graphics, so Athlon wins on brute force since it has a much better FPU.
So, this is probably how Intel demo'ed their 3.5GHz P4 last year. Shows how pointless the whole thing is, to be honest.
No: the 3.5GHz P4 Intel demoed at IDF last fall was air-cooled. On the other hand, it was certainly hand-picked from a special run of chips on a boutique process tuned to produce a few very high clocking chips at the expense of overall yield. Which, yes, shows how pointless the whole thing is, to be honest.
On the other hand, the fact that they are showing it off is an indication of where they're going. Intel showed of an (air-cooled) 2 GHz P4 at IDF fall '00, and launched the same part, not coincidentally, exactly at IDF fall '01. They showed a 3.5 GHz P4 at IDF fall '01, which means...?
No, they probably won't get one out quite so early (3.0 is more like it), but it'll be here around the end of the year. Incidentally, the top speed of an air-cooled hand-picked chip on a special process is probably more relevant to future clock scaling than that of a Liquid Nitrogen cooled off-the-shelf part, for the simple reason that the process will be tweaked to be more aggressive as time goes on, but the temperature is never going to magically drop to -196 deg C. (And yes, the difference matters, as lower temperatures attack different limiting factors for clock rates than tweaked processes do.)
